It is a mobile application that reduces fast-fashion waste through clothing up-cycling and donation
PROBLEM & RESEARCH

Spill the tea - Why Gen Z trusts people over research?
It is a social discovery platform designed to discover authentic coffee spots through recommendations
PROBLEM & opportunity

This shift presents an opportunity to create a more engaging way to discover and recommend coffee and matcha spots.
